How does reflective waveguide work
WebHolograms work by reflecting certain wavelengths of light. In this way, the incident light is reflected at a certain angle in regard to the hologram. ... The glass reflective waveguide technique is used by Lumus. This technique uses the TIR principle and an array of polarized reflectors to expand the pupil and extract the light towards the eye ... WebDec 1, 2005 · Fig. 3 is the multiple reflection signals waveform recorded by the precision reflectometer, the wavelength used in the measurement is set to 1550 nm. Because of the rapid power attenuation induced by waveguide propagation loss and waveguide facet transmission loss, only four reflection signals can be recorded by the precision …
